a suffix occurring in loanwords from Latin, its English distribution paralleling that of Latin. The form originated as a suffix added to a-stem verbs to form adjectives (separate). The resulting form could also be used independently as a noun (advocate) and came to be used as a stem on which a verb could be formed (separate; advocate; agitate). In English the use as a verbal suffix has been extended to stems of non-Latin origin: calibrate; acierate.
a specialization of -ate, used to indicate a salt of an acid ending in -ic, added to a form of the stem of the element or group: nitrate; sulfate. Compare -ite.
a suffix occurring orig. in nouns borrowed from Latin, and in English coinages from Latin bases, that denote offices or functions (consulate; triumvirate; pontificate), as well as institutions or collective bodies (electorate; senate); sometimes extended to denote a person who exercises such a function (magistrate; potentate), an associated place (consulate), or a period of office or rule (&hasp;protectorate). Joined to stems of any origin, signifies the office, term of office, or territory of a ruler or official (caliphate; khanate; shogunate).
